rpi: tizen-boot-rpi4: fix hard-coding value about ramdisksize

Current ramdisksize is set to hard-condig value as 0xc00000 or 0x800000.
If ramdisk's size is changed to other, it also needs to change.
But we're getting the number of block about ramdisk partition.
Use its value to load a ramdisk image. Then it's more clear than now.
